SPINNING-SPINDLE.

SPECIFICATION forming part of Letters Patent N 0. 701,808, dated June 3,1902.

Application filed April 4, 1901.

To all whom, it may concern:

Beit known that I,WILLIAM G1HoN,a'citizen of the United States, and aresident of Chicopee, in the county of Hampden and State ofMassachusetts, have invented a new and Improved Spinning-Spindle, ofwhich the followin g is a full, clear, and exact description.

The purpose'of the invention is to'provide an improved speed-spindle forspinning, spooling, warping, and twisting threads or yarn and to provideself -adj usting ball-bearings for the spindle. v

A further purpose of the invention is to so construct the spindle thatthe spool or bobbin will be securely retained in position thereonirrespective of whether the spool or bobbin would otherwise fit looselyand, furthermore, to provide a means whereby the spool or bobbin may beremoved from the whirl without disconnecting any parts of the device orinterfering with any of its mechanism. 7

Another purpose of the invention is to so construct the improved spindlethat it will be self-oiling, it being unnecessary torenew the supply ofoil except at long intervals of time.

vide a simple durable easy-running spindle which will not tend to heatup or break the yarn or thread.

The invention consists in the novel-construction and combination of theseveral parts, as will be hereinafter fully set forth,and pointed out inthe claims. I

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a longitudinal vertical section through the improved spindleand a support therefor. Fig. 2 is a horizontal section takensubstantially on the line 2 2 of Fig. 1 and Fig. 3 is a horizontalsection through the spindle, taken substantially on the line 3 3 of Fig.1.

The body of the spindle consists of a casing A, which casing is open atthe top and closed at the bottom and is of cylindrical shape. Thiscasing is provided with an interior annular shoulder near its bottom,whereby the upper portion of the casing A is of greater diameter thanits lower portion, as is illus- Serial No. 54,295. (No model.)

trated in Fig. 1. The casing A is provided at the top with an exteriorcollar 11, the bottom of which collar forms a bearing 12, adapted torest upon a support B, to which the easing A may be secured, and "thecasing A is usually attached to said support through the medium of anexterior thread, as is also shown in Fig. 1. V

At the upper end of the casing A an annular depression or recess 13 ismade in the collar 11, adapted to receive the lower end or portion of awhirl 14, whereby the Whirl may have vertical and guided movement in theupper portion of the casing.

This whirl 14: is of the usual construction, but is provided with anupper sleeve extension 15, exteriorly conical and provided at its upperend with longitudinal slots 16, so that any spool or bobbin capable ofbeing carried by the whirl may be placed upon the sleeve extension 15and securely held in position thereon, since the upper end of the sleeveextension of the whirl l l is in the nature of aspring, and this springportion of the sleeve extension of the whirl 14 is contracted when thebobbin or r V spool is placed in position. Another purpose of theinvention is to pro- The spindle 17 is passed through the sleeveextension 15 of the whirl 14, through the said Whirl, and into thecasing A, extending into said casing to a point near its bottom. Thewhirl 14 is attached to the spindle 17 in any suitable or approvedmanner.

A recess or chamber 18 is made in the bottom portion of the whirl 14,and within the casing A at a point below the whirl14 a cone v19 isconnected with the spindle 17 in a slidable manner; but the cone isadapted to turn with the said spindle, and this adjustable connectionbetween the spindle 17 and cone 19 is formed by passing a screw 20 orlike device through the cone 19 and into a longitudinal slot or recess21, made in the spindle, as is also shown in Fig. 1, so that the cone 19may have limited longitudinal movement on the said spindle. the spindle17, and thisspringbears against the upper portion of the cone 19.andenters the chamber 18 in the whirl 14 and has hearing against the upperwall of said chamber.

This spring 22 serves as a cushion for the upper cone 19.

In connection with the upper cone 19 a ball A spring 22 is coiled aroundrace 23 is provided, which ball-race is provided with suitable pocketsfor balls 24, which engage with the lower tapering end of the cone 19,as shown in Fig. 1. This ball-race 23 is provided with adownwardly-extending sleeve 25, through which the spindle 17 is looselypassed, and an inner sleeve 26, connected to the main sleeve 25, servesto keep the balls 2i in position. A second cone 27is attached to thelower end of the spindle 17, and this cone has also sliding longitudinalmovement on the spindle, but less movement than the upper cone 19. Thetapering surface of the lower cone 27 faces upward, and the cone isconnected with the spindle 17 by a screw or pin 28 or its equivalent,which is loosely passed into a suitable recess or aperture made in thespindle 17, as shown in Fig. 1. A ball-race 29 is provided for the lowercone 27, and in this ball-race a pocket is formed which receives theballs 30, the balls being held in position by an inner sleeve 31,fitting loosely around the spindle 17 and secured to the outer sleeve32, which forms a portion of the lower ball-race 29. The lower portionof the lower ball-race 29 rests upon the shoulder 10 at the bottomportion of the casing A.

The main sleeve 32 of the lower ball-race 29 is provided with anextension-sleeve 33 of greater diameter of bore than that of the bore ofthe main sleeve 32, and this extensionsleeve 33 of the lower ball-race29 passes loosely around the downwardlyextending sleeve 25 of the upperball-race 23, as is also shown in Fig. 1. A slot 35 is made in theextension-sleeve 33 of the lower ball-race near the bottom portion ofsaid sleeve, and a screw 34 or its equivalent is passed through thecasing and into the said slot 35, thus holding the spindle and itsball-races and cones in position within the casing A. A second pin orscrew 37 is passed through a longitudinal slot 36, made in the upperportion of the extension-sleeve 33, and this pin or screw 37, which islocated entirely within the casing A, is secured to thedownwardly-extending sleeve 25 of the upper ball-race 23. A spring 38 iscoiled around the spindle 17 between the two ball-bearings, and thisspring rests upon the upper end of the main sleeve 2 of the lowerball-race and against the bottom of the sleeve 25, which extendsdownward from the upper ball-race 23. The spring 38 serves as a cushionfor both of the ball-races, so that the spindle can operate with butlittle friction and but little wear, and by means of the two cushions 22and 38 the spindle 17 and the whirl 14 may be lifted upward a requireddistance should a bobbin or spool cling to the extension of the whirlwithout detriment to the various parts of the device and without causingthe parts within the casing A to leave the same.

It will be observed that the casing A constitutes a well in which alubricant may be placed and that therefore the spindle is renderedself-lubricating. It is evident that oil placed in the casin g will lastfor a great length of time.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. The combination with a spindle, and a whirl, of aball-bearing operatively engaging said spindle and having the conemember of said bearing slidably connected to the spindle to rotatetherewith, and a cushion-spring engaging with said whirl and said conemember of the bearing.

2. The combination with a spindle, and a casing, of independentball-bearings spaced relatively to one another on the spindle and eachbearing having a cone member connected by a loose joint to said spindlefor rotation therewith, and a cushion-spring interposed between saidbearings, whereby the spindle may be partly forced outward by thecompression of said spring.

3. In a spinning-spindle, the combination, with a casing, a spindleextending within the casing, and a whirl attached to the said spindle,of spring-controlled ball-bearings for the spindle, the cones of whichbearings are attached to the spindle and have limited movementlongitudinally of the spindle, and means, substantially as described,whereby one spring-cushion is located between opposing ball-bearings anda second spring-cushion is located between the whirl and adjacentball-bearing, as set forth.

4. The combination with a casing, and a spindle, of separatebearing-cups arranged to have limited movement relative to one another,bearing-cones revoluble with the spindle and disposed in cooperativerelation to said bearing-cups, suitable bearing-balls, and acushion-spring disposed between and in operative relation to saidbearing-cups.

5. The combination with a casing, and a spindle, of bearing-cups looselyheld Within said casing and slidably connected together for movementrelative to one another, bearing-cones cooperating with saidbearing-cups and connected to said spindle so as to rotate therewith andto have a limited slidable play thereon, a cushion-spring tending tonormally separate the bearing-cups and retain them in operative relationto the cones, and suitable bearing-balls.

In testimony whereof I have signed my name'to this specification in thepresence of two subscribing witnesses.

\VILLIAM GIHON.
